ILLUSTRATED LETTER ENVELOPE Filed June 15, 1935 INVENTOR UBALDO SORRENTINO BY H I I ATTORNEY Patented Sept. 1, 1936 lTED STATES TET OFFICE 3 Claims.

This invention relates to new and useful improvements in an illustrated letter envelope.

The invention has for an object the construction of an article as mentioned which is charac- 5 terized by a sheet of material bent at its center to have superimposed outer and inner sections, and a flap associated with one of the sections in such a manner that the sections may be folded and the flap pasted down to form a sealed en- 1 velope.

More particularly, the invention contemplates arranging the flap on the outer section, and imprinting the outer face of the inner section with pictorial illustrations or other printed matter to enhance the saleability of the article.

A further object of the invention is the provision'of score lines to guide the folding of the sections so that the top and bottom ends may be folded inwards and the folded article folded along 20 its center to produce the envelope efiect.

Still further the invention contemplates the provision of means for sealing the open sides of the envelope to more securely maintain the contents thereof.

25 Another object of the invention is the construction of an article as mentioned which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention,

30 and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:-

Fig. 1 is a perspective view of an article constructed according to this invention and shown in the opened position.

40 Fig. 2 illustrates the article in the closed position.

Fig. 3 is a fragmentary View similar to a portion of Fig. 2 but illustrating another embodi- 4 ment of the invention in which there is provision for sealing the ends of the envelope.

Fig. 4 is a fragmentary perspective view of the article shown in Fig. 3 in a partially closed position.

50 The illustrated letter envelope, according to this invention, comprises a sheet of material l0 bent at its center ID to have superimposed outer and inner sections lii and m respectively. A flap l I is arranged upon the end of the outer 55 section and is of narrower width than the said section. The outer face of the inner section lo is adapted to receive writing, and preferably is imprinted with pictorial illustrations l2 or other material calculated to enhance the sale of the article. 5

A pair of parallel score lines l3 extend from the ends of the flap II across the sections Ill and A third score line I4 extends at rightangles to the score lines l3 and through the center of the sections. The edge of the flap II is 10 provided with gummed material I5 by which it may be pasted down.

The article may be closed and sealed in the following manner: The portions of the sections I!) and !0 outside of the score lines l3 should be bent inwards along these score lines. The sections should then be folded upon the score line M. The article is now in the condition illustrated in Fig. 2 and may be sealed by moistening the gummed material I 5 and pasting down the flap.

The article in the condition shown in Fig. 2 may be bowed open by pressing together the top edge and the bottom edge and allowing the sides thereof to spread apart. This permits partial inspection of the contents. In Figs. 3 and 4 a means has been provided for sealing the ends of the envelope to prevent this bowing open, which means is arranged in such a manner that it may be easily torn open without destroying any portions of the letter itself.

More particularly, the means mentioned in the previous paragraph consists of a longitudinal bent strip of material IE3 at each side of the flap I 5 and adapted to individually seal each side together. More particularly, each strip l6 consists of an arm lfi and an arm l6 connected together by a bent portion E6. The outer faces of the arms Is and I6 are gummed so that they may be moistened and pasted down when desired. The arm l6 is slightly longer than the arm lG so as to have an additional area I 6. This additional area is pasted down upon the flap l5 and is the sole means for supporting the strip. Consequently, the strip I8 may be folded away from its position over the sections I0 and I0 when desired. A thin Wire or cord I1 is extended along the bend l6 and projects at the area |6.

The envelope may be sealed in a manner very similar to the sealing of the form shown in Figs. 1 and 2, except for the addition of the sealing qualities of the strips i 6. The strips I6 are lifted free from the section 48 The areas of the sections w and lfi are then bent inwards along the score lines IS. The article is then folded on the score line It. The strips it are next engaged between the front and rear portions along the edges thereof, as clearly shown in Fig. 4, and moistened so as to seal the ends of the envelope together. The flap H may then be pasted down.

When the envelope is opened, the flap I5 is first torn. Then the wires or strings H are pulled so as to tear the strips I6. The illustrated letter may then be opened.

.While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:-

- 1. In an illustrated letter envelope, a sheet of material bent at its center to have superimposed o-uterand inner sections, a flap on the end of said outer'section and'of narrower width than said section, the free face of the inner section being adapted to receivewriting and being imprinted with matter calculated to enhance the saleability of the'article, a 'pair of parallel score lines from the ends of the flap across said sections, and a third score line at right-angles to said score line and through the center of said sections.

'2. In an illustrated letter envelope, a sheet of material bent at its center to have superimposed outer and inner sections, a flap on the end of said outer section and of narrower width than said section, the free face of the inner section being adapted to receive writing and being imprinted v with matter calculated to enhance the saleability absence of the article, a pair of parallel score lines from the ends of the flap across said sections, and a third score line at right-angles to said score line and through the center of said sections, whereby the areas of the sections outside said pair of score lines may be bent inwards and the sections bent over on said third score line to form the envelope shape, and a strip bent centrally along the longitudinal direction and attached at its end on Said flap and extending inside and along said pair of score lines to said third score line and having gummed material on the outer sides thereof for sealing the ends of the envelope closed.

v3. In an illustrated letter envelope, a sheet of material bent at its center to have superimposed outer and inner sections, a flap on the end of said outer section and of narrower width than said section, the free face of the inner section being adapted to receive writing and being imprinted with matter calculated to enhance the saleability oi the article, a pair of. parallel score lines from the ends of the flap across said sections, and a third score line at right-angles to said score line and through the center of said sections, whereby the areas of the sections outside said pair of score lines may be bent inwards and the sections bent over on said third score line to form the envelope shape, and a strip bent centrally along the lon- V gitudinal direction and attached at its end on said flap and extending inside and along said pair of score lines to said third score line and having gummed material on the outer sides thereof for sealing the ends of the-envelope closed, and strings along the bends of said strips and pasted in positiOn.
